JERSEY. ASSIGNOBS TO THE SAFE-CABINET CGMPANY, 0F MARIETTA, OHIO, A COR- PORATION or OHIO.

To all w/eom it may (ONCM'WI Be it known that we, :RALI'H ll. llnin and lu'rru lV1(l;lNll')N. both citizens of the United States. and rcsidi-nis. rrriprctivrly, oi Marietta, lvnshington rount Ohio, and

invented it rrrtnin new and usrfnl Inigo-mu ment in Doors for Salon or tliillii l. of which tllu following is a flWCillClllIlflll.

(by invention relates to doors intcndcd fog-Tho on rnhincts or light weight safes used as containers for \nlnnhlc rrrords, drurumcnts and similar nrticl and is dcsigned especially to prevent. th: entrance of heat to tho intcrior of tho null: or cnhinct and to furnish :in additional safeguard to the contents thcreot in case in :1. fire. thiextcrior front of the cute or cabinet ohould be destroyed or damaged, either h) t long: (OIL tinned period of excessively high tcmpcrw ture or by it full resulting from the giving Way of the floors of the building in which the safe or cabinet is located.

WY accomplish this by using a door con structcd in a manner and of materials which will resist the entrance of hunt to the interior of the cabinet 0 snlc with on especial regard to circumventing such cntrnncc of high temperatures along the lines of tho structure whcro the materials having the greatest hcut conductivity are located. Tho details of tho construction are shown in the drawings horcwith of a preferred form and describe-(l in the ffOllOWlllfl spccificntion1-- Solid metal doors are open to tho objection that they constitute good conductors of heat, and Wu have also found in our rxporiments and tests that by insulating any and all metal parts which might constitute lines of heat communication from the. exterior to the interior of the safe or cuhinot, at much greater safety to the contents is assured.

In the drawings l-.crcwith:--

As'shown herewith 10 indicates the outer walls of the safe or cabinet and 1111'are tho inner walls which surround the space within which the various papers, documents, ctc, are contained. Between the outer walls 10 and 11, in the space 12 an of the usual forms of insulation may e employed.

Patented Feb. 3, 1920; Application filed Kay 3. 2918. Serial No. 238,277. I

While our construction can be used on either single or double doors; we show here double doors in. which 13 is the outer front wall, 14

the inner wall, with hinges 15-15 and handlcs 16----1fi intended to operate the bolt rods 17-47 which in turn move the locking bolts 1 8-18.

As shown the door consists of sheet metal shnpcd to form the outer walls with angular projections as at 19 which fit closoly into correspondingspacos in the jamb of the rnhinct or safe, thereby providing a broken or tortuous channel to delay the entrance of heat through the openings at the hi At 21] wall is bent inwardly and ends at the oint ill--21, a heat insnlatin material 2 22' in the walls 19-19 and 2424, in the handles l6-l6; and in the combination look (not shown) either ends or is parted at the point of this air space. Any heat conducted from the exterior by any of theso iuetul hurts to the air space 523 would naturally be absorbed or distributed throu bout this air space the surrounding, wals of which are almost entirely of an insulating material of low conductivity.

20,011 either side of the door, this 11161581- In actual practice an excessively high temperature sometimes occurs at a. particular spot at the exterior of the safe or cablnot and this may result in the weakening or breaking down of the insulating mate rial adjacent to that particular spot, which would permit the heat to proceed toward the interior of the safe or cabinet. The air space 23 would serve in a case of this kind to take up and distribute this excessive heat instead of compelling the insulation directly between the interior and the weakened spot to bear the whole load.

The insulating material 22 may be of any of the known types and may be of either a dry nature or constituted so that under a, high temperature, moisture in the form of vapor may be given off to reduce the temerature and wet down the contents of the interior of the safe or cabinet.

To secure the inner part of the door to the outer part, we use the smell catches 2626 of any usual form. They should be of sufficient strength tocstend any ordinary strain but light enough in construction to a low the outer or front part of the door to separate from the inner section, if by ajnll or in any other manner the front section should be thrown out of its normal position.

The locking device, comprising the hendles 1616, bolt rods 17-17 and bolts 18-- 18, also serves from the nature of its construction to permit of this separation of the two sections, as, while when the two sections are secured together by the catches 26-26, the double bolts 18-18, operated by the handles 16-16 and the rods 17- 17, en-

page with the frame of the safe or cabinet to iold the outer and inner door sections in their proper respective positions, if the outer section should move outwardly from the inner section the bolts 18-18 in the inner section will remain in position and will be detached from the rods lT lT at the point 27-27.

It will thus be seen from the foregoing description that in this door for safes or cabinets there is no metal line of heat conductivity from the exterior to the interior that is not broken by insulation and a dead air space. In addition if an insulation material containing chemically bound moisture is used, the va or released under high temperatures won d flow freely into the air space 23 where it would equalize and consume the heat that might enter.

As stated above we show in the drawings herewith a preferred form of our invention, but We do not desire to be limited. strictly thereto, as the principle involved can be adapted to single doors and other modifications may be made without departing from the spirit or scope thereof.

A door for a fire-heat resisting documentreserving cubinet or safe comprising an inner member composed of a sheet metal casing and a slab of non-conducting material set therein, an outer member composed of a sheet metal casing and a slab of nonconducting material set therein, and connecting means between said members hold ing them in spaced relation, the non-con ductin slab portions being exposed op osite each ot er and said connecting means 'ieing attached thereto.
